The experiment was conducted under the open field conditions during two consecutive growing seasons. Two Cucurbita pepo summer squash cultivars: Lebanese and Zucchini Grey which are commercially grown in Iraq were chosen for this investigation. Compound fertilizer, NPK /18:18:5/ was added as side dressing in three levels: 0, 500, 1000 kg/ha. A total of six experimental treatments representing all possible combinations were set in a randomized complete block design with three replications. Data were recorded for several growth and yield components characters. The highest estimates for plant height, number of branches and leaves/plant were obtained from plants fertilized with 1000 kg/ha. While, highest total yield, fruit weight and diameter/plant resulted from plants treated with 500 kg/ha.
